Continuous and quantitative electroencephalography changes of case 2. a Baseline EEG showing diffuse slowing, maximum in the left hemisphere. b box indicates the area of worsening exam with decrease in rhythmicity especially on the right, worsening asymmetry, and increasing burst suppression ratio. c After osmotherapy is administered (black arrow), there is a return in rhythmicity in the right hemisphere and improvement in the asymmetry and reduction in burst suppression ratio
